Process Flow of Lithium Battery Crushing and Recycling Equipment

Lithium-ion batteries are widely used in various electronic devices and electric vehicles due to their high energy density, long cycle life and environmental friendliness. However, after being used for a certain period of time, the lithium-ion batteries will gradually lose their capacity and become waste. To effectively reuse the valuable resources in the waste lithium-ion batteries, a crushing and recycling process is required.

The process flow of lithium battery crushing and recycling equipment mainly includes the following steps:

Sorting and transportation: The waste batteries are first collected and transported to the recycling plant for processing. During the transportation process, safety precautions should be taken to prevent collisions and fires caused by battery damage.

Preliminary treatment: The waste batteries are sorted according to the type of battery and level of damage. The outer casing of the battery is removed to expose the electrode material inside.

Crushing: The exposed electrode material is then crushed into small particles. The crushing process needs to ensure the safety of personnel and equipment, and minimize the generation of dust.

Separation: The crushed material containing electrode materials and other impurities is separated using mechanical or physical methods. This step is critical in maximizing the recovery rate of precious metals.

Purification: The separated electrodes and other materials are purified using chemical methods to obtain high-purity metal oxides, which can be used as raw materials for the production of new batteries.

Disposal of waste residue: After the recycling process, there will still be a small amount of waste residue left. The waste residue contains toxic substances and needs to be disposed of safely and properly.

In summary, the process flow of lithium battery crushing and recycling equipment involves sorting and transportation, preliminary treatment, crushing, separation, purification, and waste residue disposal. Through this process, valuable resources such as lithium, cobalt, nickel and copper can be recovered, and environmental pollution can be minimized.
